The Java code pure Java code and libraries you write on one platform operating system will run on other platforms with no modification.
The JVM executes the Java bytecode. Since all JVMs works exactly the same, the same code works on other operating systems as well, making Java platform-independent.
An object-oriented Language There are different styles of programming. Object-oriented approach is one of the popular programming styles. In object-oriented programming, a complex problem is divided into smaller sets by creating objects. This makes your code reusable, has design benefits, and makes code easier to maintain.
If you are serious about programming, you should definitely learn object-oriented style of programming. Java is fast The earlier versions of Java were criticized for being slow.
However, things are completely different now. The new JVMs are significantly faster. Now, Java is one of the fastest programming languages.
